Watching Transitions
After the indirect assessment, the team's hypothesis about Kou's screaming at school was that the truck, the noisy gym or the two together might be what kept it going. The next step was descriptive assessment: recording antecedents, behavior and consequences as they occurred naturally during the school day, without changing anything. Descriptive data show what actually happens around a behavior, which indirect reports can only estimate.
Kou's paraprofessional had already kept narrative notes for three weeks before I arrived. Most entries read like this: "11:50, lining up, Kou screamed and dropped. I talked to him and calmed him down. Attention." Of twenty-two entries, eighteen ended with the word "attention."
Narrative and Structured Formats
Lerman et al. (2009) compared the accuracy of descriptive data collected by teachers using two formats. In narrative recording, teachers wrote free descriptions of what happened before and after each episode. In structured recording, they checked boxes from lists of specific antecedents and consequences. Teachers' records were compared with those of trained observers. Accuracy was generally higher with the structured format, and narrative records often omitted or misdescribed events, especially consequences.
The paraprofessional's notes illustrated the problem. "I talked to him" described her own response, which was attention, but it did not record whether the truck was returned or whether the class left for the gym without him, both of which also happened in many episodes.
Every note recorded what the adult did; almost none recorded what Kou got.
The Structured Form
With my supervisor, I designed a one-page structured form for the six daily transitions. Antecedents included: asked to put away an item, asked to line up, loud setting ahead, peer close by and adult hand-holding. Consequences included: item returned, allowed to stay in the room, verbal attention, physical comfort, and transition delayed. Each episode received one check per applicable box, so several consequences could be recorded together. I trained the paraprofessional on the form with three practice videos, and we both recorded for the first three days to check agreement, which reached 85 percent on consequences by the third day.
Two Weeks of Data
Over ten school days, the structured form recorded thirty-four episodes of screaming during transitions. Twenty-eight occurred at transitions that required putting away an item, and twenty-six occurred before transitions to the gym or the bus line, both loud settings. Only four occurred at transitions to the quiet library, and none of those involved an item being put away.
Consequences were mixed. Verbal attention followed thirty-one of thirty-four episodes, which explains the narrative notes; staff almost always talked to him. But the truck or another item was returned in twenty-three episodes, and the transition was delayed by more than two minutes in twenty-five.
Conditional Probabilities
A raw count of consequences can mislead, because a consequence that follows behavior often may also occur often when no behavior happens. I calculated conditional probabilities: the probability of each consequence given screaming, compared with its probability during transitions without screaming. I also recorded twenty transitions without screaming over the same days.
Attention followed screaming in 91 percent of episodes but also occurred in 80 percent of calm transitions, because staff routinely talked to Kou as they walked. The difference was small. Return of the item followed screaming in 68 percent of episodes but occurred in only 10 percent of calm transitions. Delay of the transition followed screaming in 74 percent of episodes and in 5 percent of calm ones. These comparisons suggested that item return and delay were more closely tied to screaming than attention was.
Why Descriptive Data Cannot Confirm Function
Thompson and Iwata (2007) compared the results of descriptive analyses with those of functional analyses for individuals with problem behavior. They found that the two methods often disagreed, and that attention frequently followed problem behavior in descriptive data even when functional analyses showed another function. Their explanation was that caregivers commonly respond to problem behavior with attention regardless of what maintains it, so attention appears in descriptive records as a matter of course.
Kou's data showed the same pattern. Attention followed almost every episode because the adults always responded verbally, not necessarily because it maintained the screaming. Even the conditional probabilities showed only correlation. Item return and delay were associated with screaming, but descriptive data cannot show whether they cause it, and the two were confounded: in most episodes, both happened together. The data narrowed the hypothesis but could not separate the two variables.
Recording Antecedents Carefully
The antecedent data were as useful as the consequence data. Screaming was rare at quiet transitions and common at loud ones, and common when an item had to be put away. Cooper et al. (2020) note that antecedent patterns can suggest motivating operations, conditions that change the value of a reinforcer. For Kou, noise ahead might make escape from the gym more valuable, and losing the truck might make its return more valuable.
A Scatterplot for Brynn
Descriptive assessment took a different form in Brynn's case, where the question was when rather than what. Her teachers marked each worksheet tearing on a scatterplot grid divided into half-hour blocks across the school week, and her mother's sleep log recorded whether Brynn had slept poorly the night before. Over three weeks, nineteen of twenty-four tearing episodes fell before 10:30 in the morning, and fifteen followed nights her mother had marked as poor. The pattern fit the setting event identified in the record review. It did not show what the tearing produced, so her teacher added two consequence boxes to the grid, work removed and adult came over, for the following three weeks. Even a simple grid can point an assessment toward the right hour.
What Comes Next
Because item return and escape from noise were confounded in the natural setting, the team planned a brief functional analysis with my supervisor to test them separately, with conditions in which only the toy, or only the quiet setting, followed screaming. The structured form would continue in the meantime to track the baseline.
Conclusion
Narrative notes recorded attention after most of Kou's screaming because they recorded what adults did. A structured form, checked for agreement as Lerman and colleagues recommend, showed that item return and delayed transitions were closely tied to screaming while attention was nearly constant. Thompson and Iwata's findings explained why descriptive data still could not confirm function, and why a functional analysis was the next step.

The Purdue Global BA430 Unit 5 instructions
Unit 5 in BA430 asks you to collect and evaluate descriptive assessment data. Describe a case, real or composite, and the recording format used, and compare narrative and structured formats using research on accuracy. Report antecedent and consequence data across a defined period, and check agreement between observers. Calculate conditional probabilities and compare them with the same events during periods without problem behavior. Explain what the data suggest about function and why descriptive data alone cannot confirm it. Include a time-based method such as a scatterplot if useful. Close with the next assessment step. Write about five pages in APA format with composite clients, labeling figures as illustrative. Report agreement for each observer pair.
How the BA 430 Unit 5 example is put together
The paper opens with narrative notes ending in the word attention. A section summarizes Lerman and colleagues on narrative and structured formats, under a highlighted line that the notes recorded what adults did rather than what Kou got. A section describes the structured form and agreement checks. A section reports thirty-four episodes and their antecedents and consequences. A section calculates conditional probabilities against calm transitions. A section applies Thompson and Iwata to explain why attention appears so often, followed by notes on antecedents, a scatterplot for Brynn's tearing and her sleep, and the plan for a functional analysis to separate confounded variables. The closing paragraph restates why the analysis is needed and what each condition will test.
BA430 Unit 5 rubric: what earns full points
Graders assessing this paper look for data treated as correlations, with a clear statement that descriptive assessment cannot establish function. Comparing consequences after behavior with their rates when no behavior occurs shows statistical understanding beyond counting. Structured recording with agreement checks earns credit, especially when it corrects an earlier format. Explaining why attention commonly appears in descriptive records reflects the research. Confounded variables should be identified and linked to a next step. Antecedent patterns and setting events add depth. Research on recording accuracy and on descriptive versus functional outcomes belongs in APA style, with clients described as composite. Tables of probabilities are useful. Show your base rates.
Common BA430 Unit 5 mistakes, and how to avoid them
Descriptive assessment papers often treat the most frequent consequence as the function. Others use narrative notes without checking their accuracy. Students frequently skip conditional probabilities or calculate them without a comparison period. Confounded consequences, which happen together, are commonly missed. Some papers conclude function from descriptive data alone. Before submitting, record a set of calm periods and compare each consequence's rate with and without problem behavior. Check agreement on at least a few sessions. Name any two variables that always occurred together and how you will separate them. Mention antecedent patterns. Keep students composite and figures illustrative. Then end with the step that will test function directly, such as a brief analysis with a supervisor.

BA430 Unit 5 questions, answered
What is ABC recording?
Recording antecedents, behavior and consequences as they occur naturally.
Are teacher-collected data accurate?
Accuracy improves with structured formats and training.
Can descriptive data identify function?
They show correlations, not causes, so they may suggest but not confirm function.
Where can I find a free BA430 Unit 5 sample paper?
This page holds the complete BA430 Unit 5 paper analyzing structured ABC data for a composite nine-year-old's screaming.
Why was attention misleading in the BA430 Unit 5 sample?
Staff talked to the student in 80 percent of calm transitions too, so attention after screaming was nearly a constant.
